Hi.

I have a 2016 IS 350 F Sport. The car is great. Except when I am on the highway and going at 50 and above, I have this feeling like on a boat that is rocking ("rolling?") along the front-to-back axis (it's hard to describe). Nothing major, but the car doesn't feel completely level and stable. I did not notice this when I test-drove a 2015 model.

I checked tire pressure after the car has cooled off using an external gauge and one of them was off by almost 10%). I fixed that and things improved. But the feeling isn't entirely gone.

A few more data points: when I switch to Sport S+, it feels more stable than "Eco". Also, I have Adaptive Variable Suspension, but not Variable Gear-Ratio Steering (but I don't think that the latter matters).

Is anyone experiencing the same? Could my suspensions be not up to spec?

Thank you in advance for your thoughts.

Thanks for the suggestion. Is there a way I can check this on my own? I forgot to mention that I did take it to the dealership a month ago and they told me "that's how the car drives." Hmmm... I'm not so sure my head should be bobbing right and left.

I recommend having your alignment checked.
